Make Everyone Okay

This really is a very creative , but extremely difficult puzzle game by moving the head ( moving any one head, adjacent the head will move accordingly ) , and ultimately succeed in the forum so that all are showing OK ( yellow ) status . Only about sliding head , moving head will change the status of the three states in circulation in the red ( anger ) , blue ( sad ) , yellow (OK). Tell everyone to kill everyone's brain cells !
